Application Med January 6, 1926. Serial No. 79,580.

My invention relates to fire-proof floor construction and particularly to that part of said construction relating to the securlng of expanded metal to the main support of the floor. The invention is desi ned to furnish means for effecting the locklng to ether ofthese elements in an economical an efiicient manner.

The annexed drawing and the following description set forth in detail certain means embodying my invention, such means constituting, however, but one of the various forms in which the principle of the invention may be embodied.

In said annexed drawing:

Figure 1 represents a plan view of a fragmentary portionof a structural assembly forming part of a.fireproof floor construction, and illustrating my invention;

Figure 2 is a side elevation of the elements shown in Fi ure 1;

Figure? 18 a transverse vertical section, upon an enlarged scale, taken in the plane indicated by the line III-III, Figure 2; and I Figure 4 is a view similar to Figure 3 before the member locking the expanded metal to the support has been driven into place.

Referring to the annexed drawing in which the same elements are denoted by the same respective "ordinals in the several views, I illustrate-a main fireproof floor support by the ordinal 1,the same being any conventional form ,of joist or other main support provided.it is formed with two spaced members, preferably u per members, between which a resilient w ge may be secured with a driving fit, as hereinafter fully explained.

The support 1 which is herein shown is a:

fragmentary section of a structural unit forming the subject matter of-other patent with an upper chord member comprlsing two' spaced bars 2-2. In ordinary fireproof floor construction, the floor is provided with lath or expanded metal securely tied to the underlying support 1 and the samev is illustrated herein by the ordinal 3.

The object of my invention is to rovide an improved assembly for locking t e lath 3 to t e support 1. I do this by means of driving, at suitably spaced intervals, wedge applications filed by me and is provided shaped resilient members 4 through the lath 3 and into the space between the members 2. The member 4 1s a wood block of about the shape shown in the accompanying drawing and preferably of a width greater than the mesh of the expanded metal 3, so that when the resilient block is driven through the metal 3, ,it distorts or possibly breaks the wires of the. same and forces the distorted or broken Wire sections downwardly against the opposed faces of the spaced bars 2 and locks these wires against said bar faces, all as lainly shown in Figure 3.

n a co-pendin application filed concurrent date herewith, I have illustrated a use of the wedge 4 as a means for fastening an improved screed clip for supporting woodfloor nailing-strips, as well as for securing the expanded metal to the underlying joist support.

Theadvantage of the structural assembly described is that thereby the lath is very quickly locked to'the main support, it being necessary for the workman only to move rapidly along the joist, hammering in quickly at the desired spacing 'a series of wed es 4. The .time consumed is not compara le to that-necessitated in the common practice of fastening the lath 3 to the main support 1 by wire ties. Also, the connection is made width greater'than the mesh of the expanded metal and intersecting the metal and fastened with a driving fit to and between the spaced members of the support.

2. A structural assembly, in fire-proof floor construction, comprising the combination of expanded metal, a main support adjacently below said metal and formed with spaced members, and means for securing the metal to the support comprising a wedgeshaped resilient member of a width greater tive opposed faces of said spaced members than the mesh of the expanded metal and and the adjacent sides of said wedge mem- I intersecting the metal and fastened with 2. her. 1 driving fit to and between the spaced mem- Signed by me this 1st day of December.
